To much gas burning

There could be several reasons why your Daihatsu Terios is consuming too much fuel. Here are some possible causes and remedies.Driving habits: Your driving habits could be the cause of the high fuel consumption. Aggressive driving, speeding, and rapid acceleration can all increase fuel consumption. To remedy this, try driving more conservatively and avoid sudden stops and starts. Tire pressure: Low tire pressure can increase fuel consumption. Make sure your tires are properly inflated to the recommended pressure levels. Air filter: A dirty air filter can cause the engine to work harder and burn more fuel. Replace your air filter regularly to keep it clean and functioning properly. Fuel injectors: Dirty or clogged fuel injectors can cause the engine to burn more fuel. Have your fuel injectors cleaned or replaced if necessary. Oxygen sensor: A malfunctioning oxygen sensor can cause the engine to burn more fuel than necessary. Have your oxygen sensor checked and replaced if needed. Spark plugs: Worn or dirty spark plugs can cause the engine to run inefficiently and burn more fuel. Replace your spark plugs regularly to keep them functioning properly. It's important to have your vehicle inspected by a qualified mechanic to determine the root cause of the high fuel consumption. By addressing the underlying issue, you can improve your vehicle's fuel efficiency and save money on gas in the long run.

Hi Kevin:
That all depends on how many litres of fuel your vehicle consumes and will vary depending on driving conditions, speed, technique, engine condition, and goodness knows what else.

Let's guess and say you're using 10 litres per 100 km.
40 divided by 10 equals 4
4 times 100 equals 400km

What you will need to do is use your rate of fuel consumption with this calculation.

You would fill up the vehicle, then divide the mileage traveled by the amount of fuel it took to fill the tank again.
So assuming you filled the tank each time, you would divide 609km by 100.4 ltr which is .1648 or 16.49 L/100km
Thats about 40 mpg.

Had similar problem on '04 Zetec. Turned out to be coil pak.

REPLACE AIR FILTER.CLEAN FUEL INJECTORS,CHECK TIRE PRESSURE.LOW TIRE PRESSURE WILL CAUSE LOT OF FUEL CONSUMPTION.CITY DRIVING WILL BURN LOT MORE GAS,STOPPING VECHICLE THEN GOING WILL CAUSE MORE GAS BURNING, YOU NEED POWER AND FUEL TO GET VECHICLE IN MOTION,BY IT BEING HOT WEATHER, USING AIR CONDITIONING TO KEEP COOL INSIDE WILL CAUSE MORE FUEL CONSUMPTION.

That fuel consumption is a bit heavy, but not excessive, depending on the driving conditions. In heavy traffic and slow town driving with a lot of stop starts it would be acceptable but on the open road in 2 wheel mode it would be excessive. Kia do not seem to manage much better than about 8-10 l/100km, even on their sedans.

Not much to be done, however there is always this:

Proper tune-up
proper tires, alignment
Proper tire inflation (this is huge)
clean air filter, perhaps an air filter that is less restrictive
proper motor oil
Be certain the engine is at proper temp, not running too cool.
I hope this may have helped,
Tom

Not normal, clean burning engine, mine has 220,000 kms's. Are you using a full synthetic oil? Tried it a couple times and it took 1 litre between oil changes. I use semi synthetic oil, no issues. How long has it been burning this amount of oil? Get to your dealer and have him fix your engine.

When was last tune-up, (plugs & wires checked), and fuel filter changed. Good place to start.
